Every second in this movie corresponds to 1 Jupiter day or about 10 Earth hours. 🌠
.
This movie began as a 16-frame animation of Voyager 1 images of Jupiter. Each of the 16 images was composed by Björn Jónsson from three Voyager frames taken through orange, green, and blue filters, which he reprojected into a cylindrical map, aligned, and then projected back into the slightly squashed spherical shape of Jupiter. (This reprojection step is necessary because around two minutes elapsed between each of the component images, which, because of Jupiter's fast rotation, would result in color ghosting if they were simply overlaid.) Jónsson selected sets of images featuring the Great Red Spot near the center of Jupiter's disk, one per Jupiter day, and reprojected them to maintain a constant position for the Spot. By holding the GRS still he highlights the motions of the clouds that happen from Jupiter day to Jupiter day.
.
Ian Regan took Jónsson's 16-frame animation (representing 16 Jupiter days or about 7 Earth days) and "tweened" it, using software to compute frames to fill in the time between each of the original 16 images. The result is a smooth animation of the motion of Jupiter's clouds.
.
Jupiter may appear slightly "washed out." Jónsson has attempted to reconstruct Jupiter's color as it would actually appear to the human eye, without exaggerating the colors. However, it should be noted that the Voyager camera systems were not sensitive to light in red wavelengths (the longest wavelength they could detect is in a region we'd call "orange"). Since Jupiter is colorful in red wavelengths, attempting to produce "true color" images from Voyager data results in slightly less colorful views than we can see with modern CCDs or our own eyes.

That’s an image of the second attempt to launch the N1 rocket into orbit.
The rocket lifted into the night sky, however, as soon as it cleared the tower, there was a flash of light, and debris could be seen falling from the bottom of the first stage.The nearly 2,300 tons of propellant on board triggered a massive blast and shock wave that shattered windows across the launch complex and sent debris flying as far as 6 miles (10 kilometers) from the center of the explosion.
Launch crews were permitted outside half an hour after the accident and encountered droplets of unburned RP-1 still raining down from the sky! The subsequent investigation revealed that up to 85% of the propellant on board the rocket did not detonate, reducing the force of the blast. However, the explosion was one of the biggest non nuclear explosions ever occured, with a power of 1 kt (1,000 tonnes of TNT

First Milky Way of the season, with Venus and Jupiter making an appearance. Technically you can always shoot the Milky Way, but it’s juicy core isn’t visible from the mid fall to mid winter. This was taken near Crowley Lake, with the town of Crowley glowing in the foreground. It was -9F out and all my camera gear, me and my dog froze...temporally.

4 billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda.⠀
Currently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years. Then, the two galaxies will collide head-on and fly through one another, leaving gassy, starry tendrils in their wakes. For eons, the pair will continue to come together and fly apart, scrambling stars and redrawing constellations until eventually, after a billion or so years have passed, the two galaxies merge.⠀

[ #TBT From March 21, 2018 ] Top Shot: Starry Sunrise | Photograph by Daisuke Matsui
.
In this image of the Milky Way over an early morning in Japan, #YourShotPhotographer Mike L. commented, ‘Great shot, Daisuke! The lovely uniformity of the trees, and the crystal white of the snow, makes an interesting contrast to the random explosion of stars that is the Milky Way. Serenity indeed.’” This photo was selected for the Daily Dozen on March 20, 2018.
